Great job on the escort zaza - a lot better than my carrier anyway.
Yes, it was Fujima, not 'Fuji'.
I am an idiot and forgot their name, as I don't see many of their ships on eBay. The Hosho and Fuso are the only ones I can think of from them at the moment.
As for Pitroad, didn't they make the Soryu and Hiryu at one point? All of the other ones I saw from them are auxiliaries, including a nice looking tanker that sold on eBay for a small fortune.
Some of the series seem to have gone OOP now, but it seems as if there are still a lot available from the official sites of Hasegawa and Tamiya. I have never visited the websites of any of these other companies.
BTW - There are also quite a few waterline series ships from the navies of other countries as well, including the UK, Germany, and the US aren't there?
